terraform-aviatrix-mc-transit-peering

Description

This module will create a full mesh transit for all gateway names provided in the transit_gateways list input variable.

Compatibility

Module version	Terraform version	Controller version	Terraform provider version
v1.0.9	v1.x	>=v6.8	>=v2.23.0

Check release notes for more details. Check compatibility list for older versions.

Usage Example 1 - Old deployment with exact same order of transit_gateways list provided

module "transit-peering" {
  source  = "terraform-aviatrix-modules/mc-transit-peering/aviatrix"
  version = "1.0.9"

  transit_gateways = [
    "GW1",
    "GW2",
    "GW3",
    "GW4",
    "GW5"
  ]

  excluded_cidrs = [
    "0.0.0.0/0",
  ]
}

Usage Example 2 - New deployment

module "mc-transit-peering" {
  source  = "terraform-aviatrix-modules/mc-transit-peering/aviatrix"
  version = "1.0.9"

  prepending = [
    {
      "GW1" : 1,
      "GW3" : 1
    },
    {
      "GW2" : 4,
      "GW3" : 2
    },
    {
      "GW2" : 2,
      "GW4" : 2
    },
  ]

  transit_gateways_with_local_as = {
    "GW1" : 65051,
    "GW2" : 65052,
    "GW3" : 65053,
    "GW4" : 65054,
    "GW5" : 65055
  }
}

Variables

The following variables are required:

key	value
transit_gateways	List of transit gateway names to create full mesh peering from. NOT REQURED if "transit_gateways_with_local_as" provided.
transit_gateways_with_local_as	Map of transit gateway names and their corresponding AS numbers. REQUIRED only when using prepending.

The following variables are optional:

key	default	value
create_peerings	true	Toggle for setting peering resource creation on or off. When set to false, it only generates the peerings output so you can use it outside of this module.
enable_insane_mode_encryption_over_internet	false	Enable insane mode over internet. Will be applied to all peerings. If you need more granularity, it is suggested to use the aviatrix_transit_gateway_peering resource directly in stead of this module.
enable_max_performance	null	Indicates whether the maximum amount of HPE tunnels will be created. Only valid when all transit gateways are each launched in Insane Mode and in the same cloud type.
enable_peering_over_private_network	false	Enable to use a private circuit for setting up peering
enable_single_tunnel_mode	false	Enable single tunnel mode. Will be applied to all peerings. If you need more granularity, it is suggested to use the aviatrix_transit_gateway_peering resource directly in stead of this module.
excluded_cidrs	[]	list of excluded cidrs. This will be applied to all peerings on both sides. If you need more granularity, it is suggested to use the aviatrix_transit_gateway_peering resource directly in stead of this module.
prune_list	[]	A list of maps for peerings that should not be created. Expects gateway name. Example: [ {"gw5" : "gw1"}, {"gw3" : "gw4"}, ]
tunnel_count		Amount of tunnels to build for insane mode over internet. Will be applied to all peerings. If you need more granularity, it is suggested to use the aviatrix_transit_gateway_peering resource directly in stead of this module.
full_mesh_prepending	null	Accepted values: numbers. If provided AS-PATH prepend will be added number of times unless specific prepending is provided in "prepending" attribute which takes precedence.
prepending	null	List of Transit Gateways pairs with their prepending numbers. Example [{"gw1":1, "gw2":3}, {"gw5":1,"gw4":1}]. Prepending is unidirectional that means gw1 would prepend just once towards gw2 but gw2 would prepend x3 towards gw1.

Outputs

This module will return the following outputs:

key	description
peerings	A map of all unique peerings between the provided list of gateways.
